1 Claim.

body portion by breakable bonding material in l which the body portionof the container and cover are shaped so as to provide a pouring spoutwhen the cover is removed. a

A further object of the invention is to provide a container of the abovetype described having a strengthening bead extending all the way aroundthe periphery of the upper end thereof, whereby when the cover isremoved a smooth and unbroken edge is provided.

These and other objects will be hereinafter more fully disclosed.

Referring to the drawing:

Figure 1 is a perspective view of the sealed container.

Figure 2 is a top plan view of the same.

Figure 3 is a sectional view 'taken along the line 3-3 of Figure 2.

The invention relates broadly to a metal container, the lower end ofwhich is circular and the upper portion of which is tapered and shapedto provide a pouring spout for the container. A bottom closure is doubleseamed to the lower circular portion of the container in the well knownmanner, and a cover cut tofollow the conformation of the spout is joinedto the other end by a soft breakable solder bond. The container body isprovided with an outwardly rolled bead extending all the way around theperiphery of the upper end thereof to which the cover is soldered. Thishead not only strengthens the mouth of the container in the region ofthe pouring lip, but also presents a smooth and unbroken surface to thehand after the soldered attached cover has been removed. The cover isprovided with an extending tongue to which a key of any well known typemay be engaged for rupturing the solder bond and removing the cover.

Referring more in detail to the drawing, the container illustrating theinvention consists of a body portion 1 to the bottom end of which isattached a closure 2. Said closure is secured to the body portion by adouble seam indicated at 3. The body portion is preferably circular atthe lower end and tapers slightly toward its upper end. It is alsoshaped so as to provide a pouring spout at the upper end thereof whichis indicated at 4 in the drawing. The body portion is shaped so that thepouring spout gradually vanishes into the body portion midway of theheight of the container. The body portion at its upper end is rolledoutwardly into a hollow bead 5. This hollow bead extends all the wayaround the periphery of the upper end of the can body including thepouring spout. One purpose of this hollow bead is to strengthen theupper end and maintain its shape, thus maintaining the shape of thespout. Another purpose of this bead is' to provide a smooth upper edgefor the can body. The can body is also provided with a bead 6 which issubstantially parallel with the bead 5 and spaced therefrom. This bead 6extends all the way around the can body and spout and strengthens thecan body and aids in maintaining the shape of the spa t.

The container is closed fiy a cover 7 which is shaped to conform to thepper end of the container and the spout. This cover 7 is dimensioned sothat when placed on the hollow head 5, extending around the peripheraledge of the container body, it will overlie the bead as indicated at 8.The cover is placed on the container body and held pressed thereagainstand a solder bond 9 is placed between the hollow bead and the overlyingedge portion 8 of the cover. This solder bond is preferably made of softsolder which produces a. hermetically tight joint to which is readilyruptured for the opening of the container. The cover 7 is provided withan extension 10 on the portion thereof overlying the spout, and thisextension 10 serves as a tongue to receive a key indicated in brokenlines at 11. The key is slipped onto the tongue and then the key isturned so as to roll the cover onto the key as indicated in dotted linesat 12 in Figure 3. In this way the solder bond is ruptured and the coverremoved.

The extension 10 is preferably turned down so as to extend substantiallyalong the wall of the container for the purpose of protecting theextension. The end 7 is preferably attached to the container body by themanufacturer of the container. The container is then filled by thepacker after which the bottom end 2 is attached thereto by doubleseaming.

When it is desired to open the container the key is placed on theextension or tongue 10 and the cover is rolled onto the key, rupturingthe solder bond and thus completely removing the cover from thecontainer. The container de-' scribed above is particularly adapted fora dispensing oil at oil servicing stations for automobiles. Oil ishermetically sealed in the containers by the oil distributor and ismarketed in these containers. The key is preferably attached to thecover by solder bonding, and is used for removing the cover after whichthe oil can be poured from the container through the pouring spout intothe receiving pipe of the crank case. This container, after it isemptied, may be readily used as a measuring container, and thestrengthening bead may be placed so as to indicate the predeterminedmeasured amount of liquid.

It will be evident that minor changes may be made in the structure asillustrated without departing from the spirit of the invention as setforth in the appended claim.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent, is:- p

A metal container including a body portion, the lower end of which iscircular and the upper part of which is shaped to form a circularportion leading into a projecting spout gradually vanishing into saidcircular body portion, said container body having an outwardly rolledbead at its upper end extending all the way around the peripherythereof, including the spout, said body portion having a strengtheningbead parallel with the bead at the end and extending all the way aroundsaid body portion including the spout, a bottom seamed to said bodyportion, and a cover resting on and overlying said bead at the upper endof the body portion of the container and secured to said body portion bya breakable solder bond, said cover at the portion thereof overlying thespout having an extension extending downwardly parallel with the wall ofthe container and adapted to receive the key on which the cover may berolled for breaking the solder bond.
